In MT4, there are only orders (pending, active, and history). In MT5 there are orders (pending), deals (opened), and positions. Learn the language.

sorry but i continue  not uderstund how is possible use  in MT4 orderclose close  the trade in base of ticket

bool  OrderClose(    int        ticket,      // ticket

the ticket is univoque for a specific trade , but in Mt5 i have (for example)

bool  PositionClose(
   const string  symbol, 

symbol is not unique  exist somthing similar in mql5 ? or  how can do close byticket ?

i finded

bool  PositionCloseBy(
   const ulong   ticket,        // position ticket
   const ulong   ticket_by      // opposite position ticket
   )

but  

const ulong   ticket_by      // opposite position ticket ???  why ????  i am in CFD i try to use  without this param ,

 if(PositionCloseBy(VarOrder1)==False)

but my editor not  highligh the keyword PositionCloseBy  and return me

It is not possible to use mt4 order code in mt5. They work differently 

You need to read the manual or look at some of the articles that cover the subject

// Function to close an order by its ticket
bool OrderClose(int ticket) {
   if (PositionSelectByTicket(ticket)) {
      double price = SymbolInfoDouble(_Symbol, SYMBOL_BID); // Get current price
      double lotSize = PositionGetDouble(POSITION_VOLUME);
      double slippage = 2; // Slippage in pips

      // Send a close order
      int result = OrderSend(_Symbol, 
                             OP_SELL, 
                             lotSize, 
                             price, 
                             slippage, 
                             , 
                             , 
                             "Close order", 
                             ticket, 
                             , 
                             clrNONE);

      // Check if order was closed successfully
      if (result > ) {
         Print("Order closed successfully: ", ticket);
